WIDGET: System Performance and GRB Prompt Optical Observations

The WIDeField telescope for Gamma-ray burst Early Timing (WIDGET) is used for a fully automated, ultra-wide-field survey aimed at detecting the prompt optical emission associated with Gamma-ray Bursts (GRBs). WIDGET surveys the HETE-2 and Swift/BAT pointing directions covering a total field of view of 62 degree x 62 degree every 10 secounds using an unfiltered system. This monitoring survey allows exploration of the optical emission before the gamma-ray trigger. The unfiltered magnitude is well converted to the SDSS r' system at a 0.1 mag level. Since 2004, WIDGET has made a total of ten simultaneous and one pre-trigger GRB observations. The efficiency of synchronized observation with HETE-2 is four times better than that of Swift. There has been no bright optical emission similar to that from GRB 080319B. The statistical analysis implies that GRB080319B is a rare event. This paper summarizes the design and operation of the WIDGET system and the simultaneous GRB observations obtained with this instrument.Comment: 19 pages, 11 figures, Accepted to appear in PAS

Juice: An SVG Rendering Peer for Java Swing

SVG—a W3C XML standard—is a relatively new language for describing low-level vector drawings. Due to its cross-platform capabilities and support for events, SVG may potentially be used in interactive GUIs/graphical front-ends. However, a complete and full-featured widget set for SVG does not exist at the time of this writing. I have researched and implemented a framework which retargets a complete and mature raster- based widget library—the JFC Swing GUI library—into a vector-based display substrate: SVG. My framework provides SVG with a full-featured widget set, as well as augmenting Swing’s platform coverage. Furthermore, by using bytecode instrumentation techniques, my Swing to SVG bridging framework is transparent to the developers— allowing them to implement their user interfaces in pure Swing

Touching the invisible: Localizing ultrasonic haptic cues

While mid-air gestures offer new possibilities to interact with or around devices, some situations, such as interacting with applications, playing games or navigating, may require visual attention to be focused on a main task. Ultrasonic haptic feedback can provide 3D spatial haptic cues that do not demand visual attention for these contexts. In this paper, we present an initial study of active exploration of ultrasonic haptic virtual points that investigates the spatial localization with and without the use of the visual modality. Our results show that, when providing haptic feedback giving the location of a widget, users perform 50% more accurately compared to providing visual feedback alone. When provided with a haptic location of a widget alone, users are more than 30% more accurate than when given a visual location. When aware of the location of the haptic feedback, active exploration decreased the minimum recommended widget size from 2cm2 to 1cm2 when compared to passive exploration from previous studies. Our results will allow designers to create better mid-air interactions using this new form of haptic feedback

Applicability of the technology acceptance model for widget-based personal learning environments

This contribution presents results from two exploratory studies on technology acceptance and use of widget-based personal learning environments. Methodologically, the investigation carried out applies the unified theory of acceptance and use of technology (UTAUT). With the help of this instrument, the study assesses expert judgments about intentions to use and actual use of the emerging technology of flexibly arranged combinations of use-case-sized mini learning tools. This study aims to explore the applicability of the UTAUT model and questionnaire for widget-based personal learning environments and reports back on the experiences gained with the two studies

User-tailored Inter-Widget Communication:Extending the Shared Data Interface for the Apache Wookie Engine

Hoisl, B., Drachsler, H., & Waglecher, C. (2010). User-tailored Inter-Widget Communication. Extending the Shared Data Interface for the Apache Wookie Engine, International Conference on Interactive Computer Aided Learning 2010, Hasselt, Belgium.This paper presents a technical solution for an Inter-Widget Communication in Mash-up Personal Learning Environments enabling the possibility to model basic workflows. It explains the technical background of the widget concept and why Inter-Widget communication can be beneficial especially for e-learning. Related approaches towards an Inter-Widget communication are reviewed and delimited to the suggested approach. Finally, the detailed procedures of the Inter-Widget communication are presented on the basis of the Wookie widget engine.LTfL

INTERACTION WITH EXPANDABLE WIDGETS

A computing device (e.g., a smartphone, a laptop computer, a tablet computer, a smartwatch, etc.) may enable a widget (e.g., application, program, etc.) to transition between a minimized (e.g., collapsed, smaller, etc.) state and a maximized (e.g., expanded, larger, etc.) state in response to user input (e.g., a tap, a long press, etc.). A minimized widget and a maximized widget may differ in various respects. For instance, the minimized widget may occupy less space on a display of the computing device than the maximized widget. Additionally or alternatively, the maximized widget may perform a greater variety of actions than the minimized widget. For example, the minimized widget may not perform actions associated with gestures that conflict with (e.g., gestures that are similar, if not substantially similar to) home screen gestures (e.g., swiping left and/or right to change screens, swiping up and/or down to display device settings, etc.) to avoid interfering with the actions associated with the home screen gestures, but the maximized widget may perform the actions associated with such gestures (e.g., to perform a scrolling action, a search action, an edit action, a delete item action, etc.). Accordingly, a user may perform a maximization gesture to maximize a minimized widget and access additional, and in some cases more complex, functionality of the widget

Widget, widget as you lead, I am performing well indeed!:Using results from an exploratory offline study to inform an empirical online study about a learning analytics widget in a collaborative learning environment

The collaborative learning processes of students in online learning environments can be supported by providing learning analytics-based visualisations that foster awareness and reflection about an individual's as well as the team's behaviour and their learning and collaboration processes. For this empirical study we implemented an activity widget into the online learning environment of a live fi ve-months Master course and investigated the predictive power of the widget indicators towards the students grades and compared the results to those from an exploratory study with data collected in previous runs of the same course where the widget had not been in use. Together with information gathered from a quantitative as well as a qualitative evaluation of the activity widget during the course, the fi ndings of this current study show that there are indeed predictive relations between the widget indicators and the grades, especially those regarding responsiveness, and indicate that some of the observed differences in the last run could be attributed to the implemented activity widget

Cross-platform Styling of Native Input Widgets on Mobile Browsers

The subject disclosure relates to modifying or “stylizing” the graphical display of a native input widget (also referred to as “standard input widgets”, “native semantic input types”, or “pickers”) in a web page displayed in a web browser, particularly a mobile web browser, so that the native input widget can be configured, for example, to appear to a user to match the visual style (e.g., font size, color, localization format) of the rest of the web page. Specifically, the graphical display of the native input widget appears to the user to be modified by layering a stylized façade element (“façade element”) over the location of the native input widget. The façade element can be configured to appear to the user to match the visual theme (e.g., font size, color, localization format) of the rest of the web page. The façade element is connected to the native input widget via an implemented event bridge between the two elements to facilitate responses to user interactions with the façade element, and consequently interaction by the user with the façade element triggers an operating system widget to appear for the selection of values by the user for the standard input widget
